Abstract

A series of notches are provided in the upright plates on one end of a parallel bar linkage connecting a cultivator rig or planter assembly to a tool bar. Coil springs are tensioned between the opposite end of the linkage and a rod and trunnion assembly that fits into the series of notches. The coil springs maintain the rod and trunnion in a selected set of notches. A handle on the rod allows the operator to walk the rod and trunnion assembly up and down the series of notches to select a different set of notches and thereby incrementally adjust the down pressure to a known value or setting. When the tool bar is raised to a transport position and the linkage pivots downwardly to a lowermost position, the spring is stretched only slightly so that down pressure adjustments can be made easily using only the handle on the rod.
